In rats, an increase in heart rate by pacing is accompanied by progressive large-artery stiffening. Whether this is also the case in humans is unknown. We enrolled 20 patients who were chronically implanted with a pacemaker because of atrioventricular block or sick sinus syndrome. Arterial distensibility was measured by an echo-tracking device. In 10 patients, the evaluation was performed on th...
Changes in arterial structure and function under trandolapril-verapamil combination in hypertension.
BACKGROUND AND PURPOSE Converting enzyme inhibition and calcium blockade alter large arteries in hypertension. However, the heterogeneity of the response according to the site of cardiovascular measurements has never been investigated. METHODS In a double-blind study, we compared for 180 days 3 hypertensive patient groups treated with verapamil, trandolapril, or their combination. Using echo-...
INTRODUCTION Patients with systemic lupus erythematosus (SLE) have recognized reduction in endothelium-dependent vasodilation. Evidence demonstrates that statins are able to improve endothelial function independently on their hypolipemic action. OBJECTIVES To evaluate the efficacy of atorvastatin in improving vasodilation in SLE patients with and without conventional risk factors for coronary...
conclusions by measuring image quality metrics, this study showed that dtd and ctd filters with the canny edge detection respectively, are better than srad filter with the canny detection for speckle suppression and details preservation in both arteries in the ultrasound images. background ultrasonic evaluation of intima-media thickness (imt) is an early marker of assessing the development of a...
The brachial artery begins as a continuation of the axillary artery and is superficial throughout its course in the arm. When it enters the cubital fossa it lies anterior to the brachialis muscle and lateral to the median nerve. In cubital fossa it lies deep to bicipital aponeurosis which separates the artery from median cubital vein. The median nerve descends along the lateral side of the prox...
Since "variation" is one of anatomy topics which helps other medical sciences, specially surgery, and gives assures surgeons of surgical operations. Thus, investigation of variations in cadavers is very important and essential.A cadaver about 50-year-old and white race was prepared and dissected at Anatomy Department of Fasa Medical School.After dissecting the left arm, it was revealed that in ...
Mental and emotional arousal are known to trigger coronary events. The relation between hypercholesterolemia, behavioral factors, and mental stress-induced alterations in endothelial function are not well defined. Flow-mediated brachial arterial vasodilation has been established as a measure of arterial endothelial function. High-resolution ultrasound was used to measure mental stress-mediated,...
BACKGROUND Elevated asymmetrical dimethylarginine (ADMA) is a novel risk factor for atherosclerosis that may impair endothelial function by interfering with endothelial nitric oxide synthesis. To gain insight into the effects of ADMA on systemic endothelial function, we examined the association between ADMA and brachial artery flow-mediated dilation (FMD) in a large population of young adults. ...
Materials and methods In this diagnostic test study, the type 2 diabetic patients were submitted to clinical and laboratory evaluation. Endothelial function was evaluated with Doppler ultrasound of the brachial artery, measuring the basal diameter and the FMD after ischemia in the forearm. ROC curves were constructed and two scores were used as reference standards to assess the risk of having a...
BACKGROUND The SCORE system is a simple, currently recommended method of cardiovascular risk assessment. The aim of this study is to determine the relationship between SCORE risk and intima media thickness (IMT) and flow mediated dilatation (FMD) in a low risk population. METHODS 119 people (59 men) without known cardiovascular disease and estimated by means of SCORE system risk < 5%, were in...
